>Could you please estimate the luminosity, Yamaoka-san?
There is no information of the parallax or the spectral luminosity
class for this object. Only the proper motion is marginally detected;
about 15 mas/yr. When we assume the transversal velocity of this star
to be 10 km/s, its distance is about 130pc, which lead M_V ~ 6. So,
it possibly is a red subgiant (luminosity class IV).
Sincerely,
Hitoshi Yamaoka
# The breakup of the space shuttle Columbia is reported as an urgent
# news also in Japan. I heartfully hope the safe of the crews.
